What is an important difference between soft and rigid contact lenses?

An important difference between soft and rigid contact lenses is that rigid lenses are designed to maintain their shape and do not conform as closely to the shape of the cornea as soft lenses do. Soft contact lenses are made from flexible materials that easily adapt to the shape of the eye, allowing them to provide greater comfort and a more snug fit on the surface of the cornea. This close fit helps maintain stability and reduces the likelihood of movement, which can enhance visual acuity and comfort during wear.

While comfortability, durability, and susceptibility to spectacle blur are relevant factors when considering contact lenses, the key distinction lies in how well the lenses conform to the eye's surface—a characteristic that predominantly differentiates rigid lenses from soft lenses.
